HVAC Duct Design
Size round and rectangular ducts, compare standard sizes, and total the pressure drop of a whole run on your iPhone or iPad.
What it does
- Round and rectangular sizes from airflow and friction rate or velocity, with imperial or metric units.
- Matching standard rectangular sizes, with a height or width you can lock and an aspect limit you set.
- Duct runs with fittings, per-section pressure drop, running total, and critical path.
- Saved jobs you can reopen and share as a plain-text summary.
